## Key Reforms Impacting Tax Planning
Japan’s FY2026 tax reform introduces several groundbreaking adjustments that high net worth individuals (HNWI) and corporations should strategize around. These changes address fairness, investment, and corporate incentives.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
### 1. Increased Tax Burden on Extremely High Incomes
- The **special deduction** for high incomes will drop from **¥330 million** to **¥165 million**, and the applicable tax rate rises from **22.5% to 30%**. That expands the pool of taxpayers impacted by this higher rate.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
- Applies to income that previously was lightly taxed due to massive deductions — this signals the government’s push toward equitable taxation. Planning should consider effective bracket crossing and staging income.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
### 2. Expanded NISA & Retirement Savings Incentives
- The NISA investment account program will be expanded: **children aged 0-17** can now open accounts with **¥600,000 annual investment limits** and **¥6,000,000 total non-taxable limits**. A strong incentive for parents looking at long-term savings.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
- The **employee standard deduction or minimum guarantee** for income from employment and pension will rise. That lowers taxable base for medium earners.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_01.htm?utm_source=openai))
### 3. R&D, Equipment Investment and Corporate Tax Credits
- Robust incentives for corporations investing heavily in **high productivity equipment**. Large sums are required: e.g. investment of ¥3.5 billion+ (¥500 million for SMEs) to qualify for new special provisions.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
- Enhanced R&D tax credits, particularly for foreign-delegated research, subject to conditions. Plays a key role for multinationals.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
## High-Net-Worth & Corporate Strategies
|
| Strategy | Why It Works |
|---|---|
| **Bracket smoothing**: Shift income to years when deductions or rates are favorable. | Helps minimize exposure to the 30% rate on high incomes and control timing of itemized deductions and bonuses.|
| **Investing via tax-efficient vehicles**: Use NISA and other investment savings accounts early for dependents. | Avoids capital gains or dividends taxation, especially for children.|
| **Accelerated depreciations / special deductions**: Place large capital equipment orders to qualify for special credits. | Reduces tax liability, boosts liquidity.|
| **Maximize foreign R&D delegation**: Foreign outsourcing of R&D (excluding drug trials) gets up to 70% credit. | Highly favorable for global corporations.|
## Example Scenario
A tech company plans to purchase ¥4.0 billion in productivity-boosting equipment in FY2026. Under the new scheme, provided they meet the criteria (investment plan, yield expectations, ministerial confirmation), a large portion of that cost may qualify for special deductions or credits. Planning acquisition timing (before threshold deadlines) is critical.
## Action Items
- Get updated income projections early to see if you’ll fall into the revised “very high income” bracket.
- Review long-term savings (e.g., child education) to use NISA effectively.
- Consult accounting to identify capital expenditure windows aligned with new credits.
- For multinationals, assess whether R&D delegation structures meet Japanese qualifying criteria.
With thoughtful planning, these reforms offer both risks and opportunities — being proactive can protect your bottom line.
